Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the relatively small part of an enzyme’s structure that is actually involved in catalysis?
A
substrate
B
cofactor
C
active site
D
enzyme-substrate complex
Explanation: 

Detailed explanation-1: -The part of the enzyme where the substrate binds is called the active site (since that’s where the catalytic “action” happens). A substrate enters the active site of the enzyme. This forms the enzyme-substrate complex.

Detailed explanation-2: -An active site is the part of an enzyme that directly binds to a substrate and carries a reaction. It contains catalytic groups which are amino acids that promote formation and degradation of bonds.

Detailed explanation-3: -In biology and biochemistry, the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction. The active site consists of amino acid residues that form temporary bonds with the substrate (binding site) and residues that catalyse a reaction of that substrate (catalytic site).

Detailed explanation-4: -The active site of an enzyme also creates an ideal environment, such as a slightly acidic or non-polar environment, for the reaction to occur. The enzyme will always return to its original state at the completion of the reaction.

Detailed explanation-5: -Every enzyme has an active site, which is a region on the surface of the enzyme where its specific substrate will bind to. A substrate is a single molecule, or a combination of molecules, that has a complementary shape to the enzyme’s active site.
